Using MediaRecorder API for screen recording on the web
At CSSConf AU 2016, Soledad Penadés gave a talk called “Real time front-end alchemy“. It was full of examples of combining MediaStreams with audio and video manipulation.
Something I didn’t know was that you can record audio and video on the browser without any plugins. You can combine audio from the microphone, video from a canvas, dynamically generated content… you name it. Even recording a window or the entire screen and exporting it as a video.
